Compress Image to 50 KB Online

Compress an image to 50 KB online for a signature or small photo. Start at 50,000 bytes, choose a suitable format and inspect fine detail before downloading.

A 50 KB limit is tight. For a signature, crop empty margins without cutting off strokes. For a small photo, keep the required dimensions and use a format the portal accepts. Large document scans may lose too much detail at this size.

Choose images, set your options and start. Basic processing needs no login; transformed outputs correct orientation and remove private metadata.

0 images in queue. DPI changes print density, not image detail. Animated and multipage images use the first frame and return a warning.

How it works
  1. Select an image. This page starts with a 50000-byte target; change it if your form specifies another limit.
  2. Choose an accepted output format and whether to allow smaller dimensions. Use strict mode when the byte limit is mandatory.
  3. Process the image, compare actual output bytes and readability, then download and check it against the upload requirements.
Current limits
  • 50 KB is 50,000 bytes. PNG can preserve transparency and sharp strokes; JPEG may be smaller for photos but cannot preserve a transparent background.
  • Guest compression runs on the server, needs no login and accepts images up to 5 MB and 12 MP within daily limits. Output can be JPEG, PNG, WebP or AVIF.
  • A target is not a guarantee. Strict mode reports an unmet limit; best-effort mode may return an oversized candidate with a warning.
Questions

Which format should I use for a signature under 50 KB?

Use PNG when transparency is required and the form accepts it. For a scanned signature on a solid background, JPEG may fit more easily. Inspect thin strokes at full size. Avoid forcing a full-page document into 50 KB if its text becomes unreadable.
